Vitamin and Mineral Nutrition Information System (VMNIS)

Indicators

This section aims to provide users of VMNIS with information on different biochemical indicators for assessing the prevalence of various vitamin and mineral deficiencies in populations. These documents are a compilation of current WHO recommendations on the topic from different sources. They summarize the currently recognized cut-offs for defining deficiencies and severity of deficiencies at the population level, and the chronology of their establishment.

The cut-offs included in these summaries are essential for identifying populations most at risk of deficiency and in need of intervention. They also permit both the monitoring of trends of vitamin and mineral deficiencies and the evaluation of the impact of interventions. Such assessments allow for the measurement of progress towards international goals of control and prevention of vitamin and mineral deficiencies.
